Abstract

Background

Recurrent dislocation of the patella in patients with below knee amputation is a known
entity. Abnormally high-riding patella (patella alta) and medial patellofemoral ligament
insufficiency in these patients predisposes them to patellar instability. The established
treatment of this problem is surgical realignment.

Case presentation

A 25 year old male patient with bilateral below knee amputation presented with bilateral
recurrent dislocation of the patella while walking on knees on uneven ground. Clinical
and radiographic studies showed patella alta. A simple shoe modification was used
to treat this patient.

Conclusions

A simple shoe modification can be used to treat such a condition which is otherwise
treated surgically.
